SWF Screen Playback Size

[COLOR=black][FONT=Verdana]Hi there,[/FONT][/COLOR]
[COLOR=black][FONT=Verdana] [/FONT][/COLOR]
[COLOR=black][FONT=Verdana]Is there any AS to determine the size of the fullscreen playback? Usually I use;[/FONT][/COLOR]
[COLOR=black][FONT=Verdana] [/FONT][/COLOR]
[COLOR=black][FONT=Verdana]fscommand(“fullscreen”, “true”);
fscommand(“allowscale”, “true”);[/FONT][/COLOR]
[COLOR=black][FONT=Verdana] [/FONT][/COLOR]
[COLOR=black][FONT=Verdana]But I would like it play back at a particular size like 800 x 600 so the rest of the screen is just a border of the documents colour. Can this AS be adapted to do what I need? [/FONT][/COLOR]

Any help would be appreciated,

Cheers!
